Module dispatch 

Bitmask Dispatch Module - Compile-Time SIMD/Scalar Selection for Bitmask Operations

Dispatcher that selects between SIMD and scalar implementations at compile time based on feature flags and target architecture capabilities.

Prefer this unless you want to access the underlying kernel functions directly.

Constants

W8

Auto-generated SIMD lane widths from build.rs SIMD lane count for 8-bit elements (u8, i8). Determined at build time based on target architecture capabilities, or overridden via SIMD_LANES_OVERRIDE.

W16

SIMD lane count for 16-bit elements (u16, i16). Determined at build time based on target architecture capabilities, or overridden via SIMD_LANES_OVERRIDE.

W32

SIMD lane count for 32-bit elements (u32, i32, f32). Determined at build time based on target architecture capabilities, or overridden via SIMD_LANES_OVERRIDE.

W64

SIMD lane count for 64-bit elements (u64, i64, f64). Determined at build time based on target architecture capabilities, or overridden via SIMD_LANES_OVERRIDE.

Functions

all_eq

Returns true if all bits are equal between two bitmask windows.

all_false_mask

Returns true if all bits in the mask are unset (0).

all_ne

Returns true if all bits differ between two bitmask windows.

all_true_mask

Returns true if all bits in the mask are set (1).

and_masks

Computes the element-wise bitwise AND of two bitmask windows for intersection operations.

bitmask_binop

Performs a binary logical operation (AND, OR, XOR) on two bitmask windows with automatic SIMD/scalar dispatch.

bitmask_unop

Performs a unary operation (NOT) on a bitmask window.

eq_mask

Computes an equality mask: output bit is true if bits are equal at each position.

in_mask

Performs bitwise inclusion: output bit is true if lhs bit is present in rhs bit-set.

ne_mask

Computes an inequality mask: output bit is true if bits differ at each position.

not_in_mask

Performs bitwise exclusion: output bit is true if lhs bit is not present in rhs bit-set.

not_mask

Computes the element-wise bitwise NOT of a bitmask window.

or_masks

Computes the element-wise bitwise OR of two bitmask windows.

popcount_mask

Returns the number of set bits (population count) in the bitmask window using fast SIMD reduction.

xor_masks

Computes the element-wise bitwise XOR of two bitmask windows.
